LUBRICATING DEVICE FOR OVERHEAD TRAVELING CRANES.

SPECIFICATION formingpart of Letters Patent No". 624,994, dated May 16,1399.

Application filed March 4, 1898.

To all whom it may concern:

Be it known that I, CLARENCE LANDFEAR TAYLOR, of Alliance, in the countyof Stark and State of Ohio, have invented certain new 5 and usefulImprovements in Lubricating Devices for Overhead Traveling Cranes; and Ido hereby declare the following to be a full,

clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to an improvement in lubricating devices foroverhead traveling cranes. p

In a large majority of the overhead travel- 5 ing cranes now in use theend carriages of the bridge run in close proximity to the walls orgirders supporting the runways, and as the axlescarrying thetrack-wheels are supported in bearings on both sides of the wheels thereis no room for self-oiling boxes opening outwardly between the wall orgirder and the ends of the axles. Hence these axles have been oiledthrough oil-holes formed in the tops of the bearings, and as these holesare necessarily small they hold but little oil, and as they are abovethe axles the oil therein is soon used up. This necessitates frequentoiling of the axles and expensive delays; and the obj eet of myinventionis to provide overhead cranes with oil-boxes of ample capacity havinglids or openings arranged parallel with the axle, so as to renderthemeasily accessible and at the same time not occupy valuable space betweenthe ends of the axle and the walls or girders.

With these ends in view my invention consists in the parts andcombinations of parts, as will be more fully explained, and pointed outin the claims.

In the accompanying drawings, Figure 1 is a view in elevation of one endof a traveling crane, showing my improved oil-boxes thereon. through oneaxle and lengthwise of the box. Fig. 3 is a view of a modification; andFig. 4 is a view in section of one end carriage of Fig. 1, showing twobearings andoil-boxes and the wheel between the bearings.

In Fig. 1, A represents a section of a traveling bridge. This bridgecomprises longitudinal'girdersB and end carriages C, mount- Fig. 2 is aview in transverse section Serial No. 672,580. (No model.)

ed on wheels, which latter travel on runways D, only one ofwhich,'however, is shown.

- In a large majority of cranes the runways are located well up to thewalls E of the build- 5 5 ing, so as to enable the trolley to cover theentire floor-space. The wheels F of the-end carriages C run on the railsof the runways D, and as each wheel is mounted on an independent axlesupported in bearings on oppo- 66 site sides of the wheel it followsthat there is no room between the outer ends of the axles and walls foroil-boxes or for outwardly-open ing lids of oil-boxes. Hence heretoforethese axles have been lubricated by the introduction of small quantitiesof oil introduced at comparatively short intervals through holes in thetop of the bearings, the holes leading down to the axles.

My invention is designed to furnish self- 70 oiling bearings, and itcomprises boxes G, removably secured to the under side of the endcarriages, eachbox carrying a supply of oil,

in which the axle moves, or which can be fed to the axle by cotton-wasteor any. other approved means. The end carriages C aresupported on theseaxles, and the boxes G, one for each end of the axle, are provided withsemicircular recesses a in the sides for the reception of the lowerhalves of the axles. These boxes are as wide as the projecting ends ofthe axles or as wide as the axle-bearings, so as not to project beyondthe axles, and are removably secured at one end to the under sides ofthe end carriages, so as to cover'and embrace the exposed portions orlower halves of the axle. Each box is closed at one end, so as to make aclose fit with the end carriage, and is provided with a slotted flangeH, each flange having'preferablya pluo rality of slots, and is securedin place by the bolts H, (only one of which is shown,) passing throughthe slots and into the end carriages. The bottom of the box ispreferably curved, and the outer end of each is inclined 5 upwardly andprovided with a hinged lid or cover I, mounted in bearings I on the topof the box. From this it will be seen that the lid or cover restsparallel with the axle, and

as it is wholly within the plane of the outer end of the axle it doesnot take up any space that could otherwise be used by the bridge,

and consequently does not rob the crane of any cross-travel.

In Fig. 3 I have shown a bridge constructed to carry two trolleys andhave shown a trolley resting on rails carried by the lower flanges ofthe bridge-girders. With this construction it will be seen that thetrack-wheels run in close proximity to the inner faces of thebridge-girders, thus rendering it impossible to interpose oil-boxesbetween the girders and axles, and it is also impossible to employaxlebearings on the outside of the wheels. To lubricate these axles, Iemploy boxes G, identical in all respects with those shown in Figs. 1and 2, and locate them under the axle and axle-bearings adjacent to theinner faces of the wheels. With this arrangement the oilboxes areaccessible from the ends of the trolley and the oil can be suppliedthereto in a quantity sufficient to last for days.

If preferred, I can provide the box with a cross-bar or abutment J,designed to hold the waste in contact with the axle and prevent itscreeping toward the opening.

It is evident that changes in the construction of the box and the mannerof securingit to the end carriage might be resorted to without departingfrom the spirit and scope of my invention. Hence I would have itunderstood that I do not confine myself to the details herein shownand-described, but consider myself at liberty to make such changes asmay come within my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination with the end carriages of an overhead travelingcrane, a plurality of wheels supporting said end carriage and an axlefor each wheel, each axle resting in bearings on opposite sides of thewheels, of an oilbox for the outer end of each axle, the said oil-b0xresting wholly under the axle-bearing and axle, substantially as setforth.

2. The combination with end carriages of an overhead traveling crane, aplurality of wheels supporting said end carriage and an axle for eachwheel, each axle resting in bearings on opposite sides of the wheels, ofan oilbox for the outer end of each axle, each oilbox being removablysecured in position underits respective axle, and each provided with alid located parallel to the axle, substantially as set forth.

3. The combination with a wheeled trolley, of an elongated oil-box openat its top and one end, and provided with semicircular recesses in itssides to receive the axle, the bottom of said box being inclineddownwardly from the open end to a point under the semicircular recessesthus forming an oil-well immediately below the axle, and a cover for theopen end of the box, the closed end of the box having an integral flangefor reinovably securing the box in position, substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

CLARENCE LANDFEAR TAYLOR.
